Heating Troubleshooting Tips
Hopefully, by checking the items on the troubleshooting list below, you can avoid an unnecessary service call. However, if these Quick Tip solutions do not solve your problem, call us or schedule an appointment online with an ESCO Service Technician. For emergency service, please call 801-266-3678.
Heating Problems
The Central Heating System is Not Heating or Working Properly
- Be sure power switch to furnace is on.
- Check that blower compartment door is properly aligned and secure.
- Check for blown fuse or tripped circuit breaker. Sometimes there is a fuse built into the furnace on/off switch in addition to the fuse or breaker in your main electrical panel.
- Is your thermostat set to the "HEAT" position?
- Is your thermostat at the proper setting? (Not the highest possible temperature!)
- If your thermostat is the programmable type, check the batteries.
- Is your filter clean? A blocked filter can reduce your unit's performance. Also, check and replace your filter on a regular basis to allow your unit to perform at peak efficiency.
ESCO Quick Tip: Keep the furnace set to a comfortable temperature during the entire day. Many times, people turn off their systems when not at home. The system takes some time to begin circulating properly heated air when it has been shut down for a while.
Remember that the furnace will not heat your home faster by setting the temperature to its limits! Set the thermostat to the proper temperature for efficient heating.

Furnace Thermostat Continues to Post the Same Message
- Make sure that your system has not been set to the highest possible temperature. Remember that a system set to a comfortable temperature will heat just as quickly as one set for maximum heat!
- Was there a recent power outage that may have caused the system to reset itself?
- If your thermostat is the programmable type, check the batteries.
ESCO Quick Tip: Many times a more serious problem has occurred due to a power outage or a lightning strike. If everything else seems normal (room comfort, run time, etc.) and resetting does not restore normal function, you can call us or schedule an appointment online for prompt service.

The Readout on the Thermostat Display is Blank
- Check to see if the thermostat indicator is switched to "HEAT" to activate the display. If this does not work, replace the existing batteries with fresh ones to see if the display functions properly.
- Some digital thermostats have a "reset" button on the pad. Press this to restore the original settings and-in some cases-the readout.
- If your thermostat is the programmable type, check the batteries.
ESCO Quick Tip: Many times when the thermostat display flashes a repeating message, the batteries need to be replaced. If you find yourself replacing the batteries more than the recommend number of times per year, a short could exist in the control panel.

For Systems on Utility Company Load Management Programs
- Are you on load management through your utility company? Check to see if the green light is displayed on the load management box. If a green light is present, the system should be working properly. If a red light is displayed, the system might have been turned off by the utility company. If there is no light displayed, then you need to call the utility company and a ESCO Comfort Consultant for service.
ESCO Quick Tip: Many times the batteries need to be replaced for the system to properly function. Also, check with the utility company if the system is not working due to load management, or you can call ESCO.
